Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fishing net cleaning machine that cleans seaweed, shellfish, coral, etc. attached to fishing nets such as fish pens in the sea, for example.

[Conventional technology]

Generally, mesh-like fishing nets such as fish cages at fish farms are hung in the sea, and seaweed, shellfish, coral, etc. are attached to these fishing nets. Conventionally, the seaweed attached to fishing nets has been cleaned by first hoisting the fishing nets ashore, drying them in the sun, and then crushing them with a roller or the like, or by having divers dive into the sea. This is done by using high-pressure water or the like to remove seaweed etc. that have adhered to fishing nets.

[The problem that the idea aims to solve]

However, the former process requires a lot of effort when each fishing net is brought ashore, and the latter process can be dangerous.

Therefore, a fishing net cleaning machine that cleans fishing nets underwater using a rotating brush has been devised and is well known. However, this cleaning method using a fishing net cleaning machine cannot be used under conditions where fishing nets are easily moved by ocean currents or waves. When a diver cleans a fishing net with a fishing net cleaning machine, he must hold the fishing net cleaning machine in the correct posture while supporting it, and move the fishing net cleaning machine while following the movement of the fishing net. Furthermore, the contact pressure of the rotating brush against the fishing net must be adjusted due to the thrust of the fishing net cleaning machine itself, making the work difficult and inefficient.

In particular, if the fishing net is made of fiber, the rigidity of the fishing net itself is weak, so there is a risk that the fishing net will get wrapped around the rotating brush during cleaning work and be damaged. However, the reality is that fishing nets made of other materials such as fibers are not used.

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a fishing net that can be cleaned efficiently and that has no risk of breakage when cleaning fishing nets made of weakly rigid fibers. The purpose is to provide cleaning machines.

[Means to solve the problem]

In order to achieve the above-mentioned problems, the present invention includes a cylindrical cleaning machine body that is movable under the sea or along a fishing net stretched underwater, a motor installed in the cleaning machine body, and a motor. a water flow generating means that is mounted on the output shaft of the motor and arranged inside the cleaning machine body; and a rotating brush that is mounted on the output shaft of the motor in parallel with the water flow generation means and arranged inside the cleaning machine main body, and that cleans the fishing net. A net-like cover provided on the cleaning machine body and located in front of the rotating brush, and a guide ring rotatably provided on the cleaning machine body and having a plurality of needle bars arranged radially. .

[Effect]

In the present invention, when the motor rotates, the water flow generating means and the rotating brush rotate.

The rotation of the water flow generation means generates a water flow that is drawn into the cleaning machine body, and the front end of the cleaning machine body, which receives thrust from this water flow, becomes attracted to the fishing net, and therefore the needle bar of the guide ring is attached to the fishing net. At the same time, the fishing net is attracted to the net-like cover.

When the cleaning machine is moved and the rotating brush is rotated to clean the fishing net, the fishing net tries to get caught in the rotating brush, but there is resistance due to the needle bar of the guide ring and the mesh cover. The resistance limits the amount of the fishing net that is pulled in to an appropriate amount, and the fishing net is reliably cleaned while maintaining appropriate contact between the fishing net and the rotating brush.

They have the same shape and the same number of holes as the above-mentioned holes, and can be opened and closed, and the opening area can be arbitrarily adjusted.

Next, the operation of this embodiment will be explained.

A fishing net 10 such as an aquaculture cage is suspended in the sea, and the fishing net 10 is cleaned by operating a winch on a ship and moving a fishing net cleaning machine 1 vertically via a wire 19. The details are explained below.

First, a winch on the ship is operated to wind up (or pay out) the wire 19 and move the fishing net cleaner 1 along the fishing net 10, and at the same time, the propeller 7 and the rotating brush 9 are rotated by the rotational driving force of the hydraulic motor 6. A water current is generated by the rotation of the propeller 7, and seawater flows through the water flow passage 8 in the cylindrical case 3 in the direction of arrow X, generating a thrust that moves the fishing net cleaner 1 itself in the direction of the fishing net 10. As a result, the front end side of the cleaner body 2 is attracted to the fishing net 10, the net-like cover 14 or the tip of the rotating brush 9 comes into contact with the fishing net 10, and each guide ring 17 is positioned above the fishing net 10, and the needle bar 18 is attached to the fishing net 10. Get into the 10 mesh.

When cleaning the fishing net 10 by rotating the rotating brush 9 while moving the cleaner body 2, the fishing net 10 is attracted to the net-like cover 14, so that the fishing net 10 is drawn into the rotating brush 9. However, due to the resistance caused by the needle bar 18 of the guide ring 17,
Due to the resistance provided by the net-like cover 14, the amount by which the fishing net 10 is drawn in is limited to an appropriate amount.

In this case, the net-like cover 1 depends on the amount of deposits attached to the fishing net 10, the size of the mesh of the fishing net 10, the size of the mesh of the net-like cover 14, the rigidity of the fishing net 10, etc.
The effect of 4 is different. For example, as shown in FIG. 4, if the rigidity of the fishing net 10 is weak, loosen the nut 13 tightening the bolt 12 shown in FIG. By moving the net cover 14 in the axial direction of the main force shaft 6A, the position of the net cover 14 is moved away from the rotating brush 9 by an appropriate amount. Since the fishing net 10 has low rigidity, although it enters the mesh of the net-like cover 14, the amount thereof is small, and the contact between the fishing net 10 and the rotating brush 9 is maintained appropriately.

Further, as shown in FIG. 5, when the fishing net 10 has high rigidity, the cover support member 11 shown in FIG.
The mounting position of the mesh cover 14 is moved toward the rotating brush 9 side, and the mesh cover 14 is moved toward the rotating brush 9 side.
The net-like cover 14 should be slightly bitten into the tip. In this case, since the fishing net 10 has high rigidity, even if the rotating brush 9 rotates, the fishing net 10 will not be entangled, and the contact pressure between the fishing net 10 and the rotating brush 9 is maintained at an appropriate level in this case as well.

When the cleaning machine main body 2 suspended by the wire 19 is moved, each needle bar 18 of each guide ring 17 is moved.
Each guide wheel 17 rolls on the fishing net 10 while entering the mesh of the fishing net 10. At that time, the cleaning machine main body 2
Even if the needle bar 18 of each guide ring 17 tries to meander,
is caught in the mesh of the fishing net 10, and the guide wheel 1
7 keeps the relative position between the net surface and the cleaner body 2 almost constant, so the contact pressure of the rotating brush 9 is kept constant, and each guide wheel 17 is guided by the mesh of the fishing net 10 while moving over the fishing net 10. rolling.

In this way, while the fishing net cleaner 1 is moved over the fishing net 10, seaweed and the like attached to the fishing net 10 are removed by the rotation of the rotating brush 9.

According to the above configuration, when the rotating brush 9 is rotated to clean the fishing net 10, the fishing net 10 tends to be caught in the rotating brush 9, but due to resistance due to the needle bar 18 of the guide ring 17, The resistance provided by the net-like cover 14 restricts the free movement of the fishing net 10, and limits the amount of the fishing net 10 drawn into the rotating brush 9 to an appropriate amount. Therefore, the fishing net 10 is prevented from being wrapped around the rotating brush 9, and when cleaning the fishing net 10 made of fibers with low rigidity, the contact pressure between the fishing net 10 and the rotating brush 9 is maintained at an appropriate level, and the fishing net 10 is
It is possible to eliminate the risk of damage.

In addition, if the size of the opening of the hole 11G of the cover support member 11 is adjusted appropriately by rotating the shutter 20 during work, the size of the water flow from the opening 11C due to the suction of the propeller 7 can be adjusted from the hole 11G. As a result, the force of suction to the net-like cover 14 of the fishing net 10 is adjusted, and the contact between the fishing net 10 and the tip of the rotating brush 9 can be maintained appropriately.

Further, when cleaning the fishing net 10 suspended in or in the sea, the cleaning can be done without using a diver by using the fishing net cleaning machine 1 suspended by the wire 19. Moreover, at that time,
The needle bar 18 of the guide ring 17 of the fishing net cleaner 1 is attached to the fishing net 10.
Fishing net cleaning machine 1
It is possible to maintain a stable cleaning work posture and perform cleaning work efficiently.

In this embodiment, the case where the fishing net cleaning machine 1 cleans the fishing net 10 in the sea has been described, but it goes without saying that it can also be applied to a fishing net suspended in a lake or a river.

FIG. 6 shows a fishing net cleaning machine 21 according to a second embodiment of the present invention, and in the first embodiment, the fishing net cleaning machine 1 has four
In the second embodiment, two guide wheels 24 are rotatably provided on a frame 23 provided at the bottom of a cylindrical case 22.
A plurality of needle bars 25 are arranged radially in each guide ring 24. A wire 19 is attached to the opposite side of the frame 23 of the cylindrical case 22.

The second embodiment also provides the same effects as the first embodiment.

FIG. 7 shows a fishing net cleaning machine 31 according to a third embodiment of the present invention. In the first embodiment, the wire 19 is attached to the upper frame 15 of the fishing net cleaning machine 1, whereas in the third embodiment Now, frame 32,3
A wire 19 is attached to the outer surface of the cylindrical case 34 between the wires 3 and 3. That is, the attitude of the fishing net cleaning machine 31 of the third embodiment is the attitude of the fishing net cleaning machine 1 of the first embodiment rotated by 90 degrees. The fishing net cleaning machine 31 of the third embodiment cleans the fishing net while moving laterally by moving the wire 19 laterally or by providing an appropriate propulsion device.

According to the third embodiment, the same effects as the first embodiment are achieved.

[Effect of idea]

As described above, according to the present invention, when the rotating brush is rotated to clean the fishing net, the fishing net tries to be caught in the rotating brush, but due to the resistance from the needle bar of the guide ring and the mesh cover. The resistance caused by this restricts the free movement of the fishing net and limits the amount of fishing net that can be drawn into the rotating brush to an appropriate amount. Therefore, the fishing net is prevented from being wrapped around the rotating brush, and when cleaning a fishing net made of fibers with low rigidity, the contact pressure between the fishing net and the rotating brush is maintained at an appropriate level, eliminating the risk of damage to the fishing net. be able to.

In addition, when the fishing net cleaning machine moves underwater or along the fishing net suspended in the water, the needle bar of the guide ring of the fishing net cleaning machine is guided by the mesh of the fishing net, thereby maintaining a stable cleaning working posture of the fishing net cleaning machine. This has the effect that cleaning work can be carried out efficiently.
